Endodontic instrument blocks provide a convenient way to keep a full set of endodontic instruments and materials ready for use. These specialized blocks and trays are designed to hold the small instruments and files used during root canal treatments. Some instrument blocks are designed just for holding and organizing files, while others include places for gutta-percha and other endodontic materials. With files being used in sequence, having them organized and quickly at the ready can make endodontic procedures much more efficient. Instrument blocks provide a great way to accomplish this.
